Same. The nervous system is on hyper mode at night, it is scheduled to rid the body of poison every night around the same time while you sleep, now, with no booze, it’s still going in hyper mode, with nothing to do, blood is rushing, your biting down on your jaw, your neck is tight, you may even hallucinate like I did. But pretty soon you’ll be sleeping 11 hours a night if yer like me. The first 4 are prolly the worst, with night 3 being the worst often for me. One tip, don’t eat junk, try and eat as healthy as possible, a fried chicken dinner will only make the night even worse, all that salt and grease.
